BALlNG-PRESS.

SPECIFICATION forming part of Letters Patent No. 682,514, datedSeptember 10, 1901.

Application filed March 29, 1901. Serial No. 53,554. (No model.)

To all whom Lt may concern: 7

Be it known that I, LEANDER WILSON, of Alpha, in the county of Henry andState of Illinois, have invented a new and useful Improvement inBaling-Presses, of which the following is a specification.

My invention relates to baling-presses of' that form which are arrangedhorizontally and are continuously operated by belt-power and in whichthe plungeris worked within the casing by toggle arms and gears,-the hayor other material being fed in laterally from the top in front of theplunger and packed by an oscillating board worked automatically, whileseparating partition-boards are intro duced behind each bale of hay,which bales are successively forced out one end of the casing betweentension devices, forming a throat or passage-way. My invention isdesigned to provide a greater compactness, strength, durability,simplicity, and power for this class of press; and it consists invarious features of improvement, which I will now proceed to describewith reference to the drawings and then point out in the claims.

Figure l is a side elevation of the press, partly broken away. Fig. 2 isa plan view of the press, partly broken away. Fig. 3 is a verticallongitudinal section. Fig. 4 is a similarview through a portion of thepress, showing another position of parts. Fig. 5 is a horizontal sectionin about the plane indicated by line 5 5 of Fig. 1. Fig. 6 is a verticaltransverse section on line 6 6 of Fig. 3. Fig. 7 is an end view from theleft-hand side of Fig; 1, and Fig. 8 is a detail.

In the drawings, A A A A represent the.

four longitudinally-arranged timbers of the press, which are connectedby cross-bars B B B to form the horizontal frame, which is supportedupon suitable base-bars B' B The middle part of this frame is inclosedupon its two sides and the bottom to form the feed-chamber C, Fig. 3,which opens at the top in the form of a hopper, through which the hay isintroduced and is packed or fedby an oscillating board 9, Fig. 1. A

plunger 4 reciprocates in one end of the feedchamber, being operated byspecially ar ranged toggle arms and gears, hereinafter described, whileon the left of the feed-chamber toggle=arms 3 and 3.

the extension of the frame forms the balingchamber with tension devices,through which the bales are pushed out one after the other in acontinuous fashion.

I will first describe the construction and operation of the plunger andthe oscillating feed-board, referring more especially to Figs. 1, 2, 3,4:, and 5.

D is the band-pulley, to which continuous rotation is given to drive thepress. This driving-pulley is on one end of shaft D, journaled in boxesat the end of the frame, and said shaft at the other end carries apinion D that meshes with a larger gear-wheel D on a shaft D, carryingtwo pinions D D". These pinions are on opposite sides of a strong metalthrust-plate 5, having flanges cm at top and bottom bolted to the endsof the timbers A and also through the metal crosspieces B. This endplate receives the end thrust of the pressing action, and on it, aboutthe center of its inner face, are formed lugs d a, between which is jo'inted one end of the short toggle-arm 3, the other longer arm a of thetoggle being jointed to the plunger 4.

The pinions D D Fig. 5, engage with the 'teeth of two main gear-wheels EE, which have long journals turning independentlyin elongated boxes inmetal side plates B B. These gear-wheels E are connected by independentlinks 6 6 to the axial pin 1') of the Said links connect with thegear-wheels by wrist-pins 6, located a distance from the center of thewheels equalto, two-thirds the distance between the center This positionand arrangement of the separate links to the joint 7 and thecircumference.

of the toggle produces the effect of permit ting the toggle-arms to belowered to a position low down between the gear-wheels, making themechanism more compact and direct in its action and also causing theplunger to be advanced to exert the pressing strain through four-fifthsof the revolution of the said wheel (shown by arrow at, Fig.3) and towithdraw the plunger by one-fifth of a revolution, (shown by arrow y,Fig. 4,) thus 11113.1(- ing a relatively slow and powerful compressionand a quick backward movement of the plunger when no work is being done.This not only gives greater power, but gives a be tied. Such -other.

longer time to feed and saves time on the back stroke. It also gives aquick and positive downward movement to the packingboard, as hereinafterdescribed. This packing-board 9 has a brace connection at the top to itsshank 9. This shank 9 is connected in alinement with itsoperating-lever7 bya metal pin 7 and a Wooden break-pin 7 the shank ofthe packing-board being inserted between the two thicknesses of theoperating-lever. This produces an important result, for there isconsiderable strain on the packing-board, and if the hay is caked ortough the connections of the board are liable to break, as the momentumof the machine cannot be arrested, and if this breaking strain comes itmerely breaks the pin 7 without doing harm to the other parts. Toprevent the packingboard from dropping down from gravity in front of theplunger when the pin breaks, which would cause the packing-board to bemashed by the advance of the plunger, the end of the shank 9 of thepacking-board is made inclined at at, so as to lock against the end ofthe operating-lever, forming a knuckle that bends in one direction, butnot in the The lever 7 is rigidly attached to a rock-shaft 7, which isjournaled in hearings on the top of the frame, and the lower end of saidlever is branched and straddles the toggle-arm 3, (see Fig. 2,) and isat its lower end connected by links 7 torthe middle togglejoint. Thiscauses the packing-board to rise and fall into the hopper, and itsmotion is differentiated like that of the plunger, so as to descend intothehopper with a quick positive packing blow and to rise more slowly.This gives a better packing action and more time for the insertion ofhay into the hopper. When a sufficient quantity of material has beeninserted into the hopper and packed by the successive advances of theplunger to form a bale, a partition-board is to be placed behind it andthe plunger, made to act thereagainst and advance the bale to a positionto partition-board is shown at 16, Figs. 3 and 4. It is held in anelevated positionin front of the hopper by the devices which Iam aboutto describe and at the proper moment is dropped automatically. This isaccomplished by a sliding shelf 12, which supports said board until thetime it is desired to fall, and said shelf is then hitched to theplunger by devices under the control of the operator, and the shelfbeing withdrawn the partition-board falls into the press-chamber infront of the plunger. The devices for temporarily connecting this shelfto the plunger are as follows: The shelf 12 slides on guides 9, Fig. 2,on each side of the upper frame-bars, and is provided with rods g, thatpass through lugs 9 coil-springs g being arranged on said rods so as tobear against the lugs g to render the shelf spring-seated, the springsholding the shelf in its forward position beneath the partition-board tosupport it in elevated position. Loosely connected to the shelf there isa hook h, which has an elongated slot through it which receives thecranked portion of a rock-shaft 1", bearing on its end a crank 1*, whichis connected by a rod r to a hand-lever Z, fulcrumed to the frame andprojecting vertically near the feedhopper. When the hand-lever isdeflected, it rocks the shaft r and lowers the hook it (see dottedlines,Fig. 4) into range of engagement by the top of the plunger, sothat as the latter moves back by the power of the driving mechanism thesame power is made to draw back the shelf against the tension of thesprings and drop the partition board. A spring 8, Fig. 1, pressesagainst the crank 1" and holds the rock-shaft in such position as tolift the hook 7t out of range of the plunger at all times, except whenat the will of the operator the lever is deflected. This auto maticmeans for inserting the partition-board is a feature of importance,contributing to the safety of the life and limbs of the opera .tor,which are frequently endangered in the act of inserting thesepartition-boards. The partition-board is held in front of thefeedchamber by means of four right angular catches m, Figs. 3 and 6, twoon each side, which project into the press-chamber and which yield andallow the partition-board to 7 pass them and then hold said boardagainst returning when the plunger moves back. These catches are forcedinwardly by springs m acting upon their outer arms. When the plungerpasses through the feed-chamber, these catches disappear from thechamber, and when the plunger recedes the hooks reappear in thefeed-chamber and retain the hay in place, so that another charge may befed into the feed-chamber. Just above the catches and near the top ofthe frame and in the feed-hopper is arranged a revolving folder 13,having longitudinal vanes which turn as the hay is squeezed past thesame in passing into the hopper and also out of the feed-chamber. Thisfolder reduces the frictional drag of the hay, and it is journaled inbearings that are spring-seated and yield upwardly, asseen in Figs. 3,4, and 6. This folder will be about one-half below the halochamber whenempty. When in operation,

the plunger-head is Withdrawn and the folder will revolve and drop intoposition, one wing or blade acting as a retainer, while the opposite onetucksin the hay and holds it in such shape that at the return of theplunger-head it will pack the hay in front of the next charge, makingeach charge separate as it is forced into the bale-chamber.

I will now describe the tension devices for the bale after it has beenformed by successive charges pushed out of the feed-chamber by theplunger. (See Figs. 3 and 7.) This consists of a yielding top board 15and two side plates H H, connected to and supported by horizontalspring-shanks I I. There are four screws n n n n, two on top of thebalechamber and one on each side, tapped through metal cross-pieces G Gand adapted to be turned down or adjusted by a wrench applied to theirsquared ends. These screws bear against coil-springs o 0, seated in cupsn 19, secured to the outer sides of the board 15 and plate H. These sideplates H have each two parallel horizontal convex surfaces with adepression between them, which permits a bale-band to be passed aroundthe bale, while the top board is fiat or plane. By giving these screws aturn to the right the tension is increased on all four sides of theemerging bale. Should wet or very damp material be fed into the press,the coil-springs in the cups will permit a slight yielding to let thebale pass out without readjusting the screws, while in baling drymaterial the tension of the spring permits of sufficient frictionalresistance on the bale to get the proper number of pounds in the bale.

In pointing out the distinctive features of the pressing mechanism Iwish to call attention to the separate links 6 6 for connecting thegear-wheels to the middle toggle-joint. This permits the toggle-arms tobe lowered and the machine made much more compact than when thedrive-wheels are connected by a rod going across from one to another andhaving only a single link. It also gives room for the forked lever ofthe packing-board to extend below the frame and be journaled directly onthe frame and be connected with the toggle-joint in a more direct andcompact way.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. A press comprising a framework with a reciprocating plunger and asingle pair of jointed toggle-arms, the outer arm being made short, anend-thrust plate jointed thereto, and the inner arm longer and jointedto the plunger, two gear wheels arranged inside the framework and onopposite sides and having on their adjacent faces wrist-pins-located atpoints between their center and circumferences, a separate linkconnecting each wristpin to the middle joint of the toggle-arm, saidtoggle-arms being arranged between said links substantially asdescribed.

2. A press comprising a framework with a reciprocating plungeigand asingle pair of jointed toggle-arms, the outer one being made short andjointed to an end-thrust plate, and
